Dietz Adapter to Gamma cc ??

Moin,

I can't puke like that again , now I've got the Dietz adapter 17015 and tried to connect it to my Gamma CC radio.

Paste pie

Help me often I also see something, look at the picture in the appendix.

So I can only connect the small lower plugs to the Gamma CC but what about the top of which includes many functions including rear LS and CheckControl function??

Don't make it what should I do with such an adapter? Or do I still have to make out myself??

To understand : From my wire harness come two plugs for the radio. The big red and the little black.
On the old Bose CD the big and the small
The middle one was not connected to the radio. In the Gamma CC the middle is occupied with the front LS.

Am I missing something or a cable???
Or isn't the 17015 the right one?

That can't be me having to make out myself, can it?
